Question

我正在尝试使用springboot将配置文件特定的属性文件值加载到我的@webservice类。我按照以下步骤进行操作，

1）

created application.properties with profile to be active
spring.profiles.active=dev

2）

Created application-dev.properties with following values
username = XXXXXXX
password = XXXXXXX
host = XXXXXXX
port = XXXXXXX
welcome.message = Development

3）

 Created @Springbootapplication class

4）

Created @configuration class for appconfig

5）使用

开始在appconfig类中读取application-dev.properties的值

代码：

public class AppConfig {
@Value("${welcome.message}")
 private String welcomeMsg;
 @Profile("dev")
@Bean
public MessageSource messageSourceDev() {
System.out.println("****Dev Profile called*****"+welcomeMsg);

当我从spring工具套件运行时，第一次欢迎消息在控制台中成功打印。

＆＃34; **** Dev Profile名为***** Development＆＃34;

但是当我尝试从我创建的@webservice类中读取属性值时，通过soap UI，

代码：

@WebService(serviceName = "SampleIF", endpointInterface   = "com.tc.services.sample.cxf.SampleIF")
public class SampleIFImpl implements SampleIF {
@Value("${welcome.message}")
private String welcomeMsg;
    @Override
public Contact CreateContract(Details details) {
    System.out.println("****Welcome Message Val*****"+welcomeMsg);

它通过抛出以下异常在appconfig.class失败

2）或具有空值的@webservice类

请帮我解决问题。

Answer 1

我复制了escenario，但我在实现中做了一些更改

这是我的application.yml

spring:
  profiles:
    active:
    - dev

这是我的application-dev.yml

welcome:
  message: Development

最后我直接从需要值的类中使用变量

@Value("${welcome.message}")
private String welcomeMsg;

Answer 2

我认为你应该在AppConfig类上添加@PropertySource（“classpath：application-dev.properties”）。

spring boot application（特定于配置文件）.properties返回null
